Is it free?
Yes — StackAHabit is completely free during the beta. No credit card, no trial timer. You're helping us shape the app, so founding testers get in at no cost.
Which phones does it work on?
Both. iOS installs from the App Store where available, and Android starts with a Google Play testing invite. Install takes about 30 seconds once you tap the link.
How is this different from other habit apps?
Most habit apps just track a daily checkbox. StackAHabit uses progressive overload — like training at the gym, each week gets slightly harder so your habits actually grow instead of flatlining. Hit your weekly target, level up; miss it, hold at the same level. You never get downgraded.
Do I have to check in every single day?
No. You set a weekly target and aim to hit the week — not a perfect daily streak. Miss a day and you can still win the week, so one slip doesn't spiral into quitting.
Can I build my own habits or only use presets?
Both. Start instantly from the curated catalog, or build a fully custom stack at your own pace with your own targets.
Is my data private?
Yes. See our
privacy policy for exactly what we store and how it's handled.
